Title: Process for preparing high molecular weight pigmented polyalkylene or polycycloalkylene terephthalates
IPC: C08G63/82
Filed: 1965-06-25
Abstract: Poly-(glycol terephthalates) are made by polycondensing a monomeric glycol terephthalate in the presence of phosphotungstic acid and a pigment.  The glycol may contain 2 to 10 carbon atoms and is preferably ethylene glycol, 1:4-butylene glycol or 1:4-dimethylol cyclohexane. The monomeric glycol terephthalate may be made by an ester-interchange reaction and at the end of the reaction triphenyl phosphite or phosphorous acid may be added to deactivate the ester-interchange catalyst.  In the examples, an ester-interchange reaction was effected between dimethyl terephthalate and ethylene glycol in the presence of zinc acetate, carbon black or P.V. fast red, and a dispersing agent which is a condensate of beta-naphthalene sulphonic acid and formaldehyde. The resulting bis-(beta-hydroxyethyl) terephthalate was then polycondensed.

Patent GB-831905-A (GB)
Title: Process for the wet production of a uranium double-fluoride
IPC: C01G43/06
Filed: 1957-08-28
Abstract: Double fluorides of uranium and an alkali or alkaline earth metal are prepared by subjecting an aqueous uranyl salt solution to the following three processes in any order, carried out in aqueous solution, namely (a) reduction by zinc, magnesium, iron, aluminium or lead; (b) introduction of a fluoride anion; and (c) introduction of an alkali or alkaline earth metal cation.  At least two of the three operations may be carried out simultaneously.  Thus a uranyl nitrate solution may be converted into uranyl sulphate by absorption on a cationic resin and elution with sulphuric acid; an alkali or alkaline earth metal cation may then be added as a carbonate and the reduction thereafter effected with mercury activated zinc after which the double fluoride is precipitated by the addition of the fluoride ion, added for example as hydrofluoric acid.  If the uranium absorbed on the cationic resin is eluted with an alkali metal sulphate solution, the alkali metal cation is introduced in the same operation. Similarly uranium nitrate may be converted into uranyl chloride by ion exchange absorption and elution with hydrochloric acid or an alkali or alkaline earth metal chloride, followed by reduction and addition of fluoride ion as before.  The fluoride ion may be introduced by absorbing for example uranyl nitrate on a cationic resin and eluting with hydrofluoric acid or by passage of the uranyl nitrate solution through a fluoride-ion-saturated anionic resin.  The alkali or alkaline earth metal cation is then added, followed by the reduction step.  The fluoride ion and the alkali or alkaline earth metal ion may also be introduced by eluting the uranium absorbed from a nitrate solution on an ion exchanger by an alkali metal fluoride solution, whereupon the solution is reduced as before.  Alternatively the uranyl nitrate solution may be reduced for example with zinc activated by sulphur dioxide and the desired double salt precipitated by adding an alkali or alkaline earth metal fluoride.
